Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To shorten warm-up time after toner replenishment, etc., by successively connecting an interlocking switch interrupting energizing a fixing heater in the case a locking member fixing a fixing unit is released from being locked. SOLUTION: The locking member 30 is attached to the fixing unit through a supporting shaft 31, and the interlocking switch 32 is attached below the member 30. When the member 30 rotates in a direction shown by an arrow, the switch 32 is turned off through an interlocking member 33, and the energizing with respect to the fixing heater of the fixing unit is interrupted. The fixing unit is attached to an image forming device, and is locked by the locking member 30, the switch 32 is turned on through the member 33, and the fixing unit starts energizing the fixing heater. Thus, the warm-up time after the removal of paper jammed in the case of paper jamming, toner replenishment and component exchange, etc., can be shortened, so that a user can immediately perform succeeding image formation.

Title: Power supply apparatus
Inventor: MURATA NORITAKA
IPC: H02M3/28
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To easily design a switching power supply by a method wherein a power-supply apparatus is provided with a switching circuit which performs an ON-OFF operation on the basis of pulses from a stabilized circuit and with a power conversion part which converts an input DC voltage into a DC voltage. SOLUTION: A DC voltage Vin is changed into a square-wave-shaped voltage when, under the control of a stabilized circuit 11, a MOSFET Q1 performs an ON-OFF operation by pulses given to the gate of a MOSFET Q11 from a pulse transformer T11, and the square-wave-shaped voltage is smoothed so as to become a DC voltage Voi. Then, under the control of a stabilized circuit 5, pulses are given to the gate of the MOSFET Q1 so as to be turned on and off, a square-wave-shaped voltage is generated at the primary winding N1 of a transformer T1, the voltage is transmitted to its secondary winding N2, the voltage is rectified by a rectifying circuit 2, and the voltage is smoothed by a smoothing circuit 3 so as to become a DC voltage Eo.  The stabilized circuit 5 controls a pulse width in such a way that the DC voltage Eo becomes a desired voltage, and the voltage is given to the gate of the MOSFET Q1. As a result, since the output voltage Voi is stabilized, a switching power supply can be designed easily.

Abstract: PURPOSE:To sample state information when an interruption occurs without increasing a hardware quantity by registering a phenomenon connected to the analysis of a fault in a report mode register, stopping an operation when the phenomenon reaches the prescribed number of times and preserving a state. CONSTITUTION:When a special interruption request signal from a special interruption request signal generation circuit 31 is outputted plural times and the value of an interruption counter 22 comes to '0', the output of a comparison circuit 24 comes to '1'. Then, the output of an AND circuit 19 corresponding comes to '0' and the output of an AND circuit 18 comes to '1'. They are reported to an error processing circuit 26 as hardware errors through a report line L2 and an OR circuit 25. In such a case, the circuit 26 executes a processing similar to a case when the hardware errors are reported by a route through a hardware error detection circuit 2, an error register 5 and the circuit 25. Namely, the circuit 26 controls a clock generation circuit 27, stops the supply of a clock for a hardware related part and preserves the state when the interruption occurs. Thus, state information when the interruption occurs can surely be sampled.

Title: Rotating electric machine
Inventor: MATSUBARA KENICHIRO
IPC: H02K9/06
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To minimize the magnetic sound radiated from a cooling fan even if a cooling fan vibrates with the vibration of a rotary shaft by electromagnetic force waves, by plural sheets of vanes of the cooling fan with one another in circumferential direction, using coupling member. SOLUTION: The heat generated in a stator 4 occupies the greater part of the heat generated in a rotating electric machine 1, and most of this heat is conducted to a housing 6 and further to the cooling fan 8 installed at the periphery of the housing 6, and here it is conducted to the outside air. It follows that the rotating electric machine 1 is cooled by this serial heat conduction, but sufficient cooling is difficult with only this, so the cooling fan 10 is coupled with a rotary shaft 2, and cooling air relatively low in temperature generated by that rotation is sent in compulsively between the cooling fans 8 so as to accelerate the cooling. In this case, a plurality of vanes 11 arranged in radial form of the cooling fan 10 are coupled with one another, using as many coupling members as it, thus the area in axial view of the cooling fan 10 is minimized.
